Possibly a silly question, but how does MLAA fit in when an application, let's say ETQW, asks for anti-aliasing? Does it ask for a specific method to be used, or is it up to the OpenGL implementation to provide whatever it thinks is fitting?

New version uploaded that does print average fps for both on and off cases.

The app always asks for a specific type (MSAA usually, but FSAA is available, and the app can ask for vendor-specific things like CSAA etc too). MLAA is not in the GL spec, so it can't be requested.

The idea was to let the user specify (via driconf or env var) when to enable MLAA, similar to Catalyst. Having a Mesa-specific GL extension for this would not see much use.

Beside this error: I'm wondering if the FPS output with the sphere is really right, but the sphere shows more FPS if the window is in the lower right corner (~600FPS). In the upper left corner I get ~250FPS. Both without MLAA. With MLAA it's ~77FPS and ~74FPS so it's not that visible but still the case.
